I have a CAI, Pypes O/R H pipe, and flowmasters. I had the H pipe welded at the seams of the H and bolted to the mid and headers, basicly like the OEM H is installed. How can I tell if it is rasp I am getting at 2500 RPM's or maybe a bad weld or loose pipe? If need be I can try to get a video up on friday.

 

im having the same problem
